An updated repost. For thousands of years, sailors have told of nighttime seas that mysteriously glowed a milky white or luminescent blue, stretching out to the horizon. Referred to as a “milky sea,” the tales date back at least to Greece and Roman times and may have provided inspiration for the “ocean of milk” from Hindu mythology.
As with so many sea stories, the challenge for scientists has been to document and study what sailors had observed far from land in remote stretches of the world’s oceans.
Now, scientists using light-sensing satellites have been able to track milky sea luminescence. And by happenstance, they now have sea level confirmation of their observations from a private sailing yacht that happened to find itself sailing in a glowing sea that coincided with the satellite observations.

I am traveling this week, so it seems like a good time to repost an old blog favorite, the remarkable story of the unsinkable Hugh Williams.
For the next fortnight, I will be a passenger on a sailing ship crossing the briny blue of the Atlantic. This seems like a good time to make an updated repost on the color blue.
